    Absent civilization, etc., our grasslands would have vast herds of livestock, burping and farting, producing methane.  But grasslands also fix a great deal of carbon in the soil.  The methane is cycled through the atmosphere, oceans, etc.  But a healthy grassland soil is (on human time scales) a more or less permanent carbon sink.

    The dictate that we all be vegetarian (and give up our non-vegetarian pets) is essentially a dictate that we plow over our grasslands and erode away that black, carbon-rich soil.  Granted that a great deal of meat is not grass-fed and the soil is plowed over anyway.  But were meat to be grass-fed and raised sustainably, it would be preferable to farming of grains, from both an ecological and carbon-cycle perspective.
